Despite a rise in the use of handheld computers in classrooms, meaningful learning with personal digital assistant (PDA) technology remains poorly studied. This article reports results from an evaluation of customized handheld data collection software, the BioKIDS Sequence, which was used during an 8-week biodiversity curriculum unit by 5th and…

Living in a drug-using society presents even children of primary age with many hazards. There are physical hazards: for example, finding used syringes and needles in the park or on the beach, or being exposed to alcohol at a family party. There are other hazards, too--legal, social and medical. Therefore, education about drugs helps children and…

The purpose of this study was primarily to explore the effects of constructivist-oriented instruction on fifth graders' cognitive structures about biological reproduction. Furthermore, such effects on different science achievers were also investigated. The subjects of this study were 69 eleven year olds in Taiwan, who were assigned to either a…

Traditionally, the arts have been absent from Jewish day schools' curricula, and have been relegated to occasional visual art classes, choral music courses, or extra-curricular classes after school hours. Lately, along with a surge of new Jewish day schools, the arts are making their way back into the Judaic study curriculum. In this paper, the…

This paper explores four students' attempts at teaching science in the real world classroom during their initial student teaching practicum, including their struggles and successes. When pre-service teachers enter their initial practicum experience they are confronted with differing teaching philosophies of their own, their university professors,…

In the process of designing and field-testing bioinformatics curriculum materials, we have adopted a three-stage, progressive model that emphasizes collaborative scientific inquiry. The elements of the model include: (1) context setting, (2) introduction to concepts, processes, and tools, and (3) development of competent use of technologically…

Recent efforts to design teacher education experiences using reflection as a philosophical orientation (Abell & Bryan, 1997) have shown that such experiences are influencing the way that teachers think about their practice, specifically teachers' personal beliefs about teaching and learning. In this paper, we introduce the design and…

The investigators sought to design an instructional unit to enhance an understanding of the nature of science (NOS) by taking into account both instructional best practices and suggestions made by noted science philosopher Thomas Kuhn. Preservice secondary science teachers enrolled in a course, "Laboratory Techniques in the Teaching of Science,"…

Laboratory exercises, field observations and field trips are a fundamental part of many earth science and environmental science courses. Field observations and field trips can be constrained because of distance, time, expense, scale, safety, or complexity of real-world environments. Our objectives were to develop an environmental virtual field…

The 2001 U.S. Supreme Court Case of Falvo v. Owasso School System (Owasso Independent School District No I-011 v. Falvo) has focused national attention on the common classroom practice of peer-grading. In a unanimous decision the court reaffirmed the popular view that students grading each others' tests is valuable, saving teachers' time and…

This article beings with two anecdotes that demonstrate that math and science are everywhere in a teacher's classroom. The challenge is to take these wonderful "teachable moments" that happen all the time and intentionally incorporate them into the curriculum. Early childhood teachers need to learn to seize these teaching and learning…

The average age of students at Lake Michigan College (LMC) is twenty-eight years old. In the current study, the application of customized internet assessment for Chemistry 101, Introductory College Chemistry, from 2001 to 2005 is compared with traditional assessment from 1996 to 2000. The authors describe the ways in which computerized assessment…

The importance of care for learners is recognised as fundamental of teaching: it is argued that teaching equally requires a care for "knowledge." Within a realist theory, to care for knowledge, moreover, must involve taking into account its relationship to the real world. The implications of this ontological consideration are worked out…

The purpose of this study is to refine Japanese elementary science activity structures by using a CSCL approach to transform the classroom into a knowledge-building community. We report design studies on two science lessons in two consecutive years and describe the progressive refinement of the activity structures. Through comparisons of student…

Evolution is the cornerstone of biology and one of the most powerful, exciting, and well-supported laws in modern science. Evolution transforms biology from a collection of unrelated observations and definitions into a coherent discipline that, among other things, helps people understand life's history and predict answers to important research…
